E.V., CarraçaI., SantosJ., MataP.J., TeixeiraSupplementary Material for: Psychosocial Pretreatment Predictors of Weight Control: A Systematic Review Update<p><b><i>Objective: </i></b>Systematically identifying pretreatment
characteristics that predict successful weight management is important
to improve intervention efficacy and clinical practice. This study
provides a comprehensive update of a 2005 review on pretreatment
predictors of successful weight management. <b><i>Methods: </i></b>Results
of 37 recent original studies from peer-reviewed journals were merged
with the results from the 2005 review. A critical appraisal of the 66
studies included was provided, and meta-analyses were performed when
feasible. <b><i>Results: </i></b>Fewer previous weight loss attempts
were the most consistent pretreatment predictor of successful weight
management, although with a small effect size. Importantly, several
variables were identified as non-significant predictors of weight loss,
showing trivial effects (e.g., eating self-efficacy). Many psychosocial
factors remain too little studied to allow reliable conclusions
regarding their predictive value. <b><i>Conclusion: </i></b>Previous
dieting attempts were identified as the soundest predictor of successful
weight management. Several factors, previously considered barriers to
successful weight management and now identified as non-predictors,
require more investigation given the limitations identified in this
review. Importantly, due to a comparably thin empirical basis for many
predictors, further research is essential to move the field forward.
Implications of the current state of research and necessary steps to
improve intervention efficacy and clinical practice are discussed</p>Correlates;Moderators;Obesity;Weight management;Success2018-02-13
